The color of nighttime skyglow may be about to undergo a radical change worldwide, according to scientists from Freie Universität Berlin and the Leibniz-Institute of Freshwater Ecology and Inland Fisheries. They predict that with a transition to LED lighting, blue light will increasingly affect the color of the night sky. The researchers developed a specific measurement device and observed that presently the nighttime skyglow over Berlin appears red during cloudiness. Their report, entitled “Red is the new Black,” was published in the Monthly Notices of the Royal Astronomical Society.
